WRIGHT TWP STP - Advanced Wastewater Treatment in Wright Township, Michigan

WRIGHT TWP STP is an advanced wastewater treatment facility located in Wright Township, Hillsdale County, Michigan. The plant serves a small community of approximately 977 residents, providing essential wastewater treatment services for the area. The plant employs advanced treatment processes, which go beyond secondary treatment to remove additional pollutants such as nutrients. With a designed capacity of 567.81 million gallons and an annual discharge volume of 264.98 million gallons, the facility operates under the regulatory framework of the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges to surface waters. The treated effluent from WRIGHT TWP STP is discharged into local waterways that ultimately drain into the Great Lakes basin, specifically Lake Erie. This region is ecologically sensitive, supporting diverse aquatic life and providing important habitat for migratory birds and fish species.

The plant discharges into local streams that flow into the River Raisin watershed, which drains into Lake Erie. Lake Erie is the shallowest and most biologically productive of the Great Lakes, supporting a rich ecosystem of fish, waterfowl, and aquatic plants. The watershed is also important for regional agriculture and recreation, making nutrient removal from wastewater critical to prevent algal blooms and maintain water quality.
